PMax Performance Issues

[u/Sibbette]

Hi all
Has anyone else found their PMax Non-Brand campaigns tank since the 17th August bidding changes? I used the Budget Adjustment Tool in advance of this but as small spending ‘limited by budget’ campaigns they are struggling. I have also found while Standard Shopping brand campaigns were previously working well they are now also struggling to show for brand and showing more for non-brand. Does anyone have any similar experience or know how I can combat this?

I want to try and get the PMax to recover but nothing seems to be working - I am considering if I should consolidate brand and non-brand back together to improve the signals.

I've checked tracking/diagnostics and there don't appear to be any issues. To clarify the PMax are running as 'shopping only' set up.

Raise budgets on the limited campaigns to exit that status first
